syntax: yaml: allow slash and period in key names

Browse Source 
Some Yaml files use path names and sometimes version numbers as keys,
even though / and . are not officially in the character set allowed
for key names (just like underscore is not), as far as I understand.

Also, do not colorize any backslash escapes as invalid
because some of them occur sometimes in value strings.

Also, colorize only the valid double-exclamation tags.
